示例代码如下：

        /// <summary>
        /// Geometry（Polygon）转Polyline
        /// </summary>
        /// <param name="pGeometry">传入的Polygon多边形</param>
        /// <returns>转换后的多段线</returns>
        public static IPolyline PolygonToPolyline(IGeometry pGeometry)
        {
            if (null == pGeometry)
            {
                return null;
            }
            IPolyline aTempPolyline = new PolylineClass();
            ISegmentCollection aTempGeometryCollection = aTempPolyline as ISegmentCollection;
            var pSegmentCollection = pGeometry as ISegmentCollection;
            for (int i = 0; i < pSegmentCollection.SegmentCount; i++)
            {
                aTempGeometryCollection.AddSegment(pSegmentCollection.Segment[i]);
            }
            return aTempGeometryCollection as IPolyline;
        }

思路：将Polygon转为SegmentCollection即线段的集合，逐段加入到Polyline的集合中。
